I like to ride 8 miles of road, hammering on the mtb, then
hit 20 miles of trail, then hammer back on road. so averaging
36-40 mile rides...

also, I have a few loops which are 15 miles of road, then
only 9 miles of trail (but it is the killer secret stash) then
blast 15 miles back. there are trails all the way to the
site, but it's then become 22 miles out, and 21 back, and adds
2.5 hours...

is this percentage of road/vs trail unacceptable ? I like it,
but would anyone like it ?

I am hoping to start a regular ride but it involves road chunks,
[only because the trail chunks in-between are totally worth it]...
and I don't want the rides to last over 3 hours.

I mean...road = pain in the bank...and I sure need that....anyone else ?
